Interesting to read that because there are conflicting news in this respect.
See, e.g., Electrek:
"The Korean electronic giant didn’t reveal a lot of information about the two new products – especially not the chemistry of the cells beyond lithium-ion. Apparently, the new prismatic cell (pictured above) is the one enabling “up to 600 km (370 miles) and that can fast charge EVs in 20 minutes”."

Though Samsung SDI's news release contains no detail on the above. Rather, it fails to mention lithium-ion o Li-Ion altogether:
